Specification forming part of Letters Patent No. 25,441, dated June 21,1859.

To all whom it may concern.-

Be it known that I, JAMES WV. CHAPMAN, of Trinity Springs, county ofMartin and State of Indiana, have invented certain Improvements inSugar-Mills; and I do hereby de cl'are that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making apart of this specification, of which- Figure 1represents a perspective view of the front part of this mill. Fig. 2 isa longitudinal section of the same.

My invention consists in the arrangement of two or more compressingwheels or cylinders in pairs, so that they can have a lateral adjustmentand be brought closer together, and separated at pleasure while themachine is in motion, described, represented, and specifiedas follows:

A represents a solid bed-piece, upon which the compressing-wheelsB Brest. These compressing -wheels are provided with cogged' teeth C, andone of them has a flange, D,which projects a little beyond the peripheryof said wheel and fits into an annular cavity, E, in the wheel B. Thisbrings the surfaces of the two wheels in close proximity, and at thesame time allows the cogs to mesh into each other. Thecompressing-wheels B B are placed on the journals F F, which are castsolid with the bearing-plates GG. These plates have a projection, H H,on their outer ends The projection H rests against the wedge I, and theprojection H rests against a shoulder formed by letting this projectioninto the bedplate A and keeps the wheel B rigidly in place.

J J are bolts which pass up through the bedplate and through thejournals F F, and receive washers K K on their ends,which serve to keepthe compressing-wheels down firmly on the seats or bearing-plates G G.

The machine is supported on legs L L, and operated, by horse or otherpower, by means of a belt-wheel or if by horse-power the horse ishitched to the end of a forked lever, N, which is bolted to the top 'ofthe drivingwheel B. The cane is fed through the pas sage P andcompressed by the rollers B B and carried on to the opposite side of themachine and deposited in a proper receptacle. The juice is pressed outof the cane and forced out through the channel B in the bed-pieceAinto atub; or it may be conveyed away by a pipe or otherwise.

S is a piece of metal let into the bed-piece A and flush-with itssurface, on which the lower edge of the compressing-wheels are made towipe, which prevents the juice from passing out the wrong side of themill. The wedge l regulates the distance between the surfaces of thecompressing-wheels and dispenses with complex machinery for adjusting vthese wheels.

I do not claim crushingrollers with flanges. Nor do I claim adjustingcrushing-rollers by means of wedges. Nor do I claim the forked leverirrespective of the arrangement or combination.

What I claim is- The combination and arrangement of the forked lever,crushing-wheels B B, bearings, and table or bed-timber, the table beingprepared with notches to receive the projections on the seat of thebearings and key-wedge, substantially as set forth.
